Each page features lyrics set to a familiar song and a simplified version of the melody's sheet music. Children can use the detachable xylophone mallet to play along with the melody. Each page is displayed horizontally so that children can see the open pages directly over the xylophone keys. When the child presses an icon button, a melody will play. At the same time, a bright LED for each note lights up in sync with the melody, so children can follow along with the xylophone mallet. In addition, children can use their imaginations and create songs on their own.
